Instead, Greene uses the 35-year-old evolutionary Tree of Life (TOL) classification system, which explains the diversity of life by matching and mapping relationships on a branching diagram or "tree." ...

“On the Origin of Species,” published twenty-two years later, includes only one diagram: an evolutionary tree. The tree of life became for biology what the periodic table was for chemistry ...

Birds are the most diverse land vertebrate on the planet, and now scientists have constructed a complete evolutionary tree of the 11,000 or so known species. This data came from hundreds of ...
